Previously we proposed a highly effective extraction-enhancing OLED display pixel structure based on embedding the top-emitting OLED inside a 3D reflective bank structure covered with a patterned high-index filler. For top-emitting OLED using transparent top electrode (e.g., TCO like ITO), optical simulation indicated that the optical out-coupling efficiency can be enhanced by nearly 2.8 times (e.g., from 24% to 68%). Here in this work, through optical simulation and design, we show that the overall optical out-coupling efficiency of such 3D OLED pixel configuration can be further enhanced by forming the distributed Brag reflector (DBR) between the top-emitting OLED and the high-index filler and strengthening the microcavity effect of the top-emitting OLED.
